在2019VS上运行不出来，咋回事？

#include<stdio.h>
struct student {     //学生信息结构定义
    int num;       //学号
    char name[10];   //姓名
    int computer, english, math;  //三门课成绩
    double average;     //个人平均分
};
int main(void)
{
    int i, n;
    struct student s1, max;    //定义结构变量
    printf("Input n:");
    scanf_s("%d", &n);
    printf("Input the student's number,name and course scors\n");
    for (i = 1; i <= n; i++)
    {
        printf("No.% d:", i);
        scanf_s("%d%s%d%d%d", &s1.num, s1.name, &s1.math, &s1.english, &);//此处提示波浪线

        s1.average = (s1.math + s1.english + ) / 3.0;  //此处提示波浪线
        if (i == 1)   max = s1;
        if (max.average < s1.average)
            max = s1;
    }
    printf("num:% d,name:% s,average:% .2lf\n", max.num, max.name, max.average);   //max.average中max提示未使用初始化内存
    return 0;
}
